stereoselective synthesis and biological activity of a novel series of tranylcypromine (TCPA) derivatives (14a–k, 15, 16), potent inhibitors of KDM1A. The new compounds strongly inhibit the clonogenic potential of acute leukemia cell lines. In particular three molecules (14d, 14e, and 14g) showing selectivity versus MAO A and remarkably inhibiting colony formation in THP-1 human leukemia cells, were assessed
我们报告一个新的系列反苯环丙胺(TCPA)衍生物的立体选择性合成和生物活性(14A - ķ,15,16),KDM1A的有效抑制剂。新化合物强烈抑制急性白血病细胞系的克隆形成潜力。特别地,在小鼠中评估了三种分子(14d,14e和14g)相对于MAOA具有选择性并且显着抑制THP-1人白血病细胞中的集落形成,其初步药代动力学。在小鼠急性早幼粒细胞白血病模型中进一步测试了14d和14e,得出14d最有效的。合成了它的两个对映异构体:(1 S,2 R)对映异构体15在生化和细胞分析中均显示出比其(1 R,2 S)类似物16高的活性。口服给药后,化合物15表现出体内功效,确定具有KDM1A抑制作用的小鼠白血病模型的存活率提高了62%。化合物15的生物学特性支持其作为癌症治疗剂的进一步研究。
